VIAVI Fiber Optic Basics Live-stream

hello my name is might be smooth thank you that's right [Music] hello my name is my D field engineer out of North Carolina hi my name is Jeff Harman I'm a systems engineer out of the great state of Texas got some logistics for the call first welcome to fiber-optic basics and handling our goal is to make this as interactive as possible more live video less slides ask questions using the chat window all comments and questions are viewable by all the attendees so please keep them professional if you ask a question outside the scope of the fiber-optic basics we may table it for a later YouTube session or we may answer at the end if we have time the live stream is being recorded they'll be available for later viewing on YouTube we do plan to do future YouTube live sessions one who certainly would be OTDR the mystical launch cable length I can think of about five different scenarios for launch cables so that one we would give you live examples and explain the differences also if you have something you'd like to see covered please request today via the chat some examples could be CWDM DWDM MPO or fiber-to-the-home I'll now go to the agenda slide and for the slides we will introduce a topic that we plan to do a camera so it's like we're doing a live demo with you on-site and then we would go to screen share so we can use camera and screen share to explain and teach topics rather than just using slides so there's our agenda we're going to cover wavelengths fiber types connectors and adapters a PC and UPC make sure everybody knows DB DBM and how to explain it attenuation bends proper fiber handling especially with regards to the fiber inspection and cleaning if you're new we'll give you some tips and tricks to help your job be a little bit easier more efficient and if your senior we expect will teach you something new and give you tips and tricks to help teach your new people so I'll go to the next slide and it covers the spectrum and that is the light that we used to transmit in telecom so we transmit in nanometers and a nanometer is for wavelength so the wavelength is a speed of light divided by the frequency so frequency is in terahertz and we divide speed of light by frequency we get nanometers now if we look at a rainbow we might all know ROYGBIV red orange yellow green blue violet those are visible colors our telecom transmissions are in the infrared spectrum that means they're invisible to our eyes I will show you a visible tool that is useful in the industry one it's a red light shooter so if I hold up a red light shooter and turn it on it shoots a red visible light it goes down to the end of the span and then the light comes out at the end in this case there's no light coming out so if I reach in and grab this fiber I got the red light flashing on the camera it might appear to be white but this tool helps us find breaks in jumpers breaks and connectors or bad connectors and if it goes all the way to the end then it helps us to verify continuity now I'll take a good jumper that is not broke I will plug it in to the red light shooter and now at the end of the jumper red light is coming out you might not see that on the camera but this helps us to identify a continuity a red light shooter commonly goes about four to five miles I will now switch to my PC software so we can see the invisible light so how do we do that right now we're looking at a fiber in face and we'll cover what that is today later on but I'm going to turn a laser on so I'm pressing a button and now I'm shooting 1310 so when I look at that image I see a white dot in the middle so even though that light is invisible to my eyes the camera is picking up 1310 in the infrared I will now change the wavelength to 1550 and as soon as I go to 1550 that visible light is not visible by the camera so sometimes an inspection scope can see infrared light and sometimes it can't if you're supposed to be on a unlit fiber or dark fiber and you see white light flashing on your inspection scope it is time to plug that fiber back in because you may have just unplugged live traffic this also brings us to safety standards I looked up the safety standards for red light and says our eyes will look away or we will blink before it hurts us that did not make me feel too safe and saying I have to look away before I get hurt so then visible light if it does hurt our eyes it's not bright you can't see it can hurt our eyes without seeing it so the rule of safety for lasers is do not look at the end of the jumper do not look into an SMP because something could be on is just a good proper safety habit next we're going to go to the next slide which shows the size of fiber so I have a little connector here and very hard to see on the camera but there are 12 little fibers I have a small screwdriver head I put it right next to it so if you can't see it just lets us know these are very small these actually have coating on them I'll try to separate I have two fibers separated if you can't see this okay these have coating on them so that are actually fairly big if you have no coating on a fiber which is plastic or colored you're looking at about the size of a human hair or just a little bit bigger so even though we handle a fiber in our hands with a jumper or a connector the fiber itself is very small next slide says we're gonna go over fiber types so the fiber town track the light travels down a piece of glass called the core it's surrounded by another piece of glass called the cladding and there's some protective coating on there to protect that favor from there we put plastic on it we put it inside a cable there's cab there's all kinds of protective stuff the core on single-mode fiber is typically about nine microns and the cladding is about 125 microns and multimode the core tends to be 50 or 60 2.5 microns and the cladding is 125 your average human hair size is about 80 to 100 microns so if the fiber is stripped down to just core and cladding it's about the size of a human hair and we said the single-mode core size is Nayan microns that's nine millionth of a meter that's about the 10th of the size of a human hair so a patch panel jumpers connectors may be fairly big the piece of glass that's carrying your traffic on single mode is 1/10 the size of a human hair so one thing we'll do now to show you the core size is we'll inspect some favors so I'm going to inspect a single-mode fiber on my camera so I will plug it in will come will cover single mode and multimode in more detail I see a white dot in the middle and that weight dot tells me it's single mode it looks like it's about 1/10 the size of the cladding the cladding is a gray circle it's a single mode fiber now I will switch over to a multimode fiber we said the core size is fifty or sixty two point five I plug in now and I see that the light in the middle is about half the size of the cladding so if you thought this was a single mode fiber you can look at the scope and tell that this is a multimode fiber and we'll give you some other ways how to identify the fiber type as well so now I will turn it over to Jeff so he can cover fiber and faces thanks Mike as Mike said in the previous slide this the actual fiber itself is 125 1.2 125 microns which is about one about the size of a human hair but when we get down to the core on the core on a single mode fibers common around 9 microns if used a magnifying glass and you looked at the end face of that fiber you still could not see the core being 9 microns it would take a high-powered microscope to see that in face when we look at fibers there are two different types of fibers out there fiber in faces there's what we call an S excuse me a PC or for a Polish excuse me physical contact and an APC for an angled physical contact a lot of folks will call them PC for polish connectors or UPC for ultra polish connectors or a PC for angled polish connectors but they're actually physical contacts is what the P and the C mean along with the a being angled I doubt anybody's gonna call you out or the fiber police are gonna come and say well that's the wrong terminology I hear every bunch of different things out there in the field if you look at the diagram there when you look at a PC connected connector those fibers in faces are not actually cut flat they're cut there they're manufactured to have a slight curve and a radius on them same thing with the a pcs and that radius is designed that so when we plug those two fibers in and they meet what we're trying to do is we're trying to mate the core the cladding and some of the outer contact area so you know the analogy I like to use when I'm out with technicians if I have two bowling balls I'm not trying to make the entire bowling ball I just want to make that center contact area so if I push those two bowling balls together I'm gonna mate in the center parts of those bowling balls now if you're out there and you've been working on fiber we have a hold one up I've got a PC here and then I have an APC now the PCs are blue connectors the APCs or green connectors and a lot of folks out in the field are saying hey we're seeing a huge shift from the blue PC connectors to the green APC connectors and folks you know why is that the answer is very simple a pcs angle power what we call angled physical connectors or angled polish connectors they're cut at an 8 degree angle so when we make those two 8 degree angles together what happens is the back reflections but we have about 125 percent less back reflection with an AP see any back reflections on that interface get reflected off into the cladding and out into the outer jacket area so losing those back reflections is really key on high speed fibers especially move as we move from 10 gig to 100 gig up to 400 gigs so also when you look at the blue and the green connectors we've got a PC and we've got a PC or UPC here the first thing I tell technicians these are not compatible they're not compatible in any way shape or form if you plug if you physically plug those in there is a high probability that you're going to do damage so I'm gonna switch over to my my PC software I'm going to bring up an APC connector now this was given to me by a technician when I was out with him pardon me share myself dang it sorry I thought I did okay sorry but that had been that my software up okay so I'm gonna plug in and what we're gonna see here this was given to me by a technician and he said that he had been given okay and it fails so he said he had been given this um this jumper this PC jumper to use on his a PC interface Oh TDR and he kept plugging this thing plugging this thing plugging this thing in and finally when Lau's out there doing some training with him he says this thing just doesn't work and when we inspected it we could see the damage from the APC onto the PC connection I could see the same damage on his OTDR and so when I explained to them that this was not compatible in any way shape or form and you can do physical damage well he did physical damage he actually let me have that fiber so that I could use it and prior to next training class is to show technicians about that damage so move on to the next one fiber jumpers and so when we look at fiber jumpers and connectors man they come in lots of different shapes and sizes there are a ton of different fiber jumpers fiber connectors out there so we talked about having our in faces as PC or a PC well then we come out and we have okay we have different types of connectors we have different types of fiber jumpers so I'm gonna hold up a couple single-mode jumpers here so I've got some single-mode jumpers and these are PC they're both blue and one of them is yellow one of them has a blue jacket is there a difference between the blue and the yellow they're both PC yes the blue jackets are what we call bend insensitive fibers now they came out with that a few years back and fibers that we're showing up we're spending sensitive fibers were showing up as blue why ordered a whole bunch of new fibers a couple weeks ago and my new fiber that I got is yellow but it is also bend insensitive so not everything is not every jacket means the same thing if I look at multimode fiber multimode fiber people say hey the fiber jumpers are orange now the connectors on a multimode fiber will always be beige remember single mode they're either gonna be green or they're gonna be blue for PC or a PC so I have this orange multimode fiber here that actually has LC connectors on it which I'll talk about in just a second there is also an aqua blue color multimode fiber which is om3 could also be om for out there for higher speed multi modes now again the fiber connectors are still beige when we go to when we start looking at the end phases we've got in phases out here we've got smaller end phases for LCS and larger end phases for our pcs out here so I've got an LC connector and I've got a UBC connector here or excuse me as the SC connector sorry and they are different they're different sizes your peer standard connectors your SC connectors are 2.5 millimeters on the ceramic ferrule that are that surrounds the fiber the LC jumpers have a 1.2 five millimeter jumper so if I look at if I bring this back up again and I look at my SCS and my L sees you notice that they are different sizes well you're seeing and as I talked about earlier we're seeing a rapid shift to the APC connectors you're also seeing a rapid shift to the LC connectors the answer is simple it's smaller it's about half the size of a Sam charlie or an SC connector so now I can get twice as many connections into the same amount of real estate as I was getting with my SC connectors now if I look at bulkhead adapters I've got a bulkhead adapter here this is a double one this happens to be green it's for a PCS I flip it this way it's for a Sam as for an SC connector I also have a smaller version which is for LC connectors this one is for PC connectors this green one here is for LC connectors now the kicker to this is as both this both the blue and the green are the exact same size only the color is different we try to color code them to try to keep people from not plugging in the incorrect fibers plugging blue in the green and green in the blue and what-have-you so inside these mating adapters bulkhead adapters whichever one you there's a hollow-core in there and there's two ports for it to plug in again this one happens to be double and that sleeve on the inside aligns that aligns the fibers as they go in there one of the common mistakes that technicians make out there when they plug in fibers because they go to plug that fiber in and they have that connector there and then they go to plug their other fiber in and they say yep we're plugged in here so it looks like I am physically plugged in and I've gotten on troubles with with technicians and things like that and what do I find when you go up there you actually push and you can hear that click and now that physical connection has taken place although if I just unplug it slightly it still looks it'll hang there it still looks like it is physically connected until it goes click so that is one of the key things that's one of the troubles that technicians will do sometimes they think they've got it plugged in also understand when I plug these fibers together and you hear that click on hear that click tells me that there is 2.2 pounds of force across that two and a half millimeter ferrule okay not much but when I break that down to the glass to the core and the cladding and some of the outer contact area that's 45,000 PSIs of pressure this will make more sense when we get into inspection and cleaning so we talked a little bit about mating sleeves I've moved on to my next slide and I got a little bit ahead of myself but there's different types of mating sleeves out there so even if you have an LC connector and you're going to an SC or whatever the case may be there are different connectors out there for you I actually have an A connector here a bulkhead adapter that is SC on one side LC on the other side so one of the questions I get asked a lot is hey Jeff all of our equipment out there are oft connectors and we've got this new equipment that's in a box and it's all LC connectors how the heck are we gonna get these to go together well there's things out there called hybrid cables so here's a hybrid cable that I have right here and this happens to be an MPO fiber on one side and Michael talked more about that in this MPO fiber is a PC because it's in green and it actually has 12 fibers in it some MPO fibers may have 24 on the breakout on the other side of this being a hybrid fiber I have 12 LC connectors here that are PC connector so they're blue so I've got green APC on one side I've got a fan-out or break out of 12 LC connectors that are PC so there are many different fibers and connectors out there you'll see you'll see older fibers out there that are um Sam Tom and Frank Charlie's so different type of connectors well sorry about that different type of connectors here I have single mode I have duplex fibers things like that so as we move into that stuff it's very important to understand that you have these mating adapters that they can't you know there's a mating adapter out there for what you need for whatever type of fiber there's hybrid fibers out there for whatever you may need can we'll move on to my next slide Jeff we do have a few questions sure in our head end I see green and blue jumpers plugged into each other should G's be changed out you also say there can be permanent damage using these I'm not sure why okay so I showed the permanent damage remember when we make that uhm excuse me the APC to an to an SC connector I told you there's 2.2 pounds of force across that two and a half millimeter ferrule but there's 45,000 psi s across the glass so you take an angled piece of glass and you plug it into a relatively flat piece of glass and there's a good chance that something can give and I showed it I showed one of those where the technician had continually done it and ended up breaking the fiber in face also he damaged his OTDR now I have gone into many head ends many cos and I've actually seen blue plugged into green and they're working circuits and it's one of those things it's a 50-50 shot if it's gonna work but if it does it's gonna be on a very low speed fiber typically one gig or less as soon as you move to 10 gig or a hundred gig or 400 gigs there's no way that that is going to happen and what you're gonna create is you're gonna create a ton of loss in that connector and it's usually about five DBS so on my arm on my fiber check Pro saw on my equipment here I'm gonna show you that so right now I'm gonna switch over to the power meter and I've got my power meter here transmitting and I'm receiving an a neg 3.53 I'll just call it a neg 3.5 DBM and I am SC 2sc here now I'm gonna flip this around here a second so give me a second here to flip these around so here's my SC 2sc and I'm gonna unplug that and I'm gonna plug in my LC how did that plugin Oh put in the wrong side here okay so now I have this and remember we were getting about a three three and a half while we just jumped up to four point seven five so almost a five DB hit from having um an APC connect or excuse me an APC connected to a PC connection so again it may work if it does it's on lower speeds would I change it out I would bring it to the attention of my managers and my engineers and at some point they will probably want to change those out especially as they move up they may they may just decide hey we're gonna upgrade in speed here and all of a sudden what was working now isn't working so hopefully that makes sense thank you Jeff and we have another question we have some older equipment that has st connectors the newer equipment we just pulled out of the box has an interfacing with a PC connectors how are we gonna make that work okay simple thing is hybrid cables so I talked a little bit about that in the previous slide there are hybrid fibers out there that you can get and you know in any connection that you want you can have a PC on one side and a PC on the other you can have an a PC on one side and st or an S you know an SC or an FC a Frank Charlie connection so there are a ton of different scenarios but cable manufacturers people that make fiber-optic jumpers can make you whatever configuration you want in whatever length you want so I'll hand this back off the mic thank you Jeff let me launch my pc software and we're going to talk about MPO next so Jeff mention we went from large connectors such as a Sam Charlie Sam Tom Frank Charlie and a lot of people like those because her fingers can easily work with them in the space of one Sam Charlie I can fit to Lima Charlie's Lima Charlie's are not very small they can be broken pretty easily they're hard to handle with our fingers a lot of people don't like them well manufactures the world I've competition real estate is an issue in a con room everything is shrinking so I'm holding up a Sam Charlie and I'm gonna put a MPO right next to it it's a little bit more rectangular but now this connector which is an MP or MTP has 12 fibers in it commonly sometimes 24 so everything gets more expensive and if we broke one fiber on a 12 fiber connector or 12 fiber jumper then we gotta replace everything so if you don't like Lima Charlie yeah we're gonna be going to NPO is more and more and more we see them in the data center but we see them on the service provide our space as well the other thing interesting about it is you may or may not be able to tell in the camera but one of these connectors has two little pins on it and the other one doesn't so normally we say a jumper is male well now I have a jumper on each hand one is pinned and one is unpin so that makes it a little tougher there's a key or not so it only goes in one way and now we have polarity if we connect these together is one going to one or is one going to twelve so compared to your traditional Sam Chartier Lima Charlie these things just get a little bit harder to work with one is green so it's a PC and the other one is a multimode it's yellow so just be aware if MPO comes you're going to need a little bit of training on those and we can host a youtube live on as well next I'm gonna go to cables so if I pop up the slide for cables we're not going to cover these too much most of us handle fibers at a patch panel with the connector or optics or SFPs we just plug in and transmit or receive it's the outdoor folks or contractors who come in to splice indoors or outdoors and they actually hand on the cables in general there's a bunch of tubes and a cable and a bunch of fibers so I do have an example here I showed you the small ones before here is some that have more coating on them I got 12 in my hand they got different colors the colors tell the outside people in splicer people which is 5 and 1/2 make sure they spliced fiber 1 to 5 or 1 and people are working with cables they're gonna get the class and they're gonna get the training and commonly there are 144 or 288 in one cable and though days I remember somebody saying why will you ever put in 4 fibers now the largest cable that I'm aware of is up to six thousand nine hundred twelve and one cable that huge fiber count we'll start to see in data centers we'll go to the next slide which is difference between idibia DBM so we need to know these terms in the telecom space and I will go to the class I say does everybody know what DBM is are they all tell me yes and I say can anybody give a class I've never had a technician give me a class so we're gonna give you two key points today the first point is DBM the M means absolute measurement and then fiber it's Miller watts and copper you could have millivolts you could have Miller amps and we speak in the milliwatts the other thing is if we go to a light bulb we might have a 20 watt bulb a 15 for outdoors 60 right light and the room is a hundred we just say we got a 10 watts 200 watts well if we go into the fiber world we can go from one watt two milliwatts to micro and that's thousands of thousands of thousands of numbers so rather than make us have watts milliwatts and microwatts and say it's 1/100 of a millimeter to dbms so now we can go from plus 32 neg 30 that's only ninety numbers right 30 up and third sixty numbers 30 up and thirty down so that means that our luck rhythmic when you do testing the tester will do the math for you so if you look on the slide and it says 10 milliwatts if you add 10 milliwatts plus 10 milliwatts that's 20 milliwatts you can add milliwatts linearly but if you add 10 DBM plus 10 DBM and say it's 20 DBM well 20 DBM is actually a hundred milliwatts so that shows that these are logarithmic we Jam a whole bunch of numbers in a small amount of space so it's easiest for us to talk notice there's a negative 10 a negative 20 that doesn't mean reflection it doesn't mean other direction it just means it's a very small amount of light one bill of watt is 0 DBM if you get a little hotter you're in plus dbms if you get a little weaker you're at negative DBMS when you do your tester it's gonna do the math for you and then I'll go to the demonstrate DV and DBMS I'm gonna use money to show this I get it from my wife's wallet I got wife and kids so I don't have money in the wallet but here I have 4 20s I call this dollars M it's real it's absolute you can touch it you can see it you can buy something but if I said I have 4 20s how much money did I lose our gain you have no idea because you don't know what I started with so in order to get DBS you have to have a reference point so in this case I say my reference point is 5 $20 bills it's $100 we're now later if I show you I have 4 20s you know that because you started with the hundred and now you have 80 you lost $20 so absolute money real measurement $80 is dollars M what I lost is gone you can't see it my kids took it that's dB it's just dollars so if you can touch it feel it or see it light is too hot light is too cold that's dbms but even have a loss that's because you did a reference and you have to have a known start point so I will go to the tester to show that I'll turn on my laser and I'll go to a power meter and the power meter says I'm getting about next three DBMS 2.88 well I'll hit a reference on the power meter when I hit that it's gonna go to zero so that's basically saying I know know how much money you have so in order to do DBS and lost urs or DBS if you want to see if a laser is hot at SP is DBMS if you just want to check light at the end of the span is DBMS so the same thing would go for weight if I said I weighed 180 pounds you might say wow Mike you look great you lost a lot of weight but if I was 120 you say why Mike you don't look great you gain 60 pounds so demonstrate DV and DBM is you got to have a reference the next thing we'll do is I'll go to the slide is we're going to talk about Benz so if we bend a fiber light can leak out of it the highway links are affected by Benz more than the lower wavelengths so typically 1310 doesn't get hit by bends too much in 1550 is five to ten times worse so I'm going to hook up to the meter now and I'm going to put some bends and show you what happens if you study some stuff it'll say Ben's safe radius as ten times the diameter of the cable maybe it's 24 outdoors I just use the soda bottle reference if I can wrap around a water bottle a drink can that is a decent radius we go into building the ducts and the full or in the ceiling are not else their s's to make sure we respect been radius and if we're going into equipment there's usually pins that we wrap stuff around and make sure we respect the bend radius so right now I'm at negative 3 DBS I'm a par meter and if I start to squeeze this I'm doing a 180 and as I squeeze I'm now at 70 B's 10 DBS 11 B B's so with a little squeeze now I'm at negative 14 oh we got 10 12 TVs of extra loss from the small cake if you kick it you can break it or if you can kick it you cost so much loss that you can make the traffic not work so we have to be very sensitive to our bend radius not so bad at 1310 but 1550 or higher wavelengths you can definitely bring down the traffic roll the card over it close the lid on something or something kink it up in the shelf and you can bring down the traffic so now I'll stop my screen share and turn it over to Jeff so he can cover some information on dirt and since we're moving from connectors loss a PC single mode good time for questions if not we'll keep going and we'll cover inspection and cleaning and dirt Mike do have a question how do you perform a reference okay so thank you and there's a couple of things for reference it depends what space we are in what do I mean by that in the enterprise space they do a one jumper reference we're a three jumper reference why is that because they have short fiber so short fiber has tiny loss eyeball it might be a little bit wrong but if we're on 100 metres of fiber at 1550 it might be point zero zero two on the fiber tiny tiny tiny you can do the math but it is tiny tiny tiny point zero something four point zero zero something if we expect a connector to have a loss of about two-five we connect on one side we connect on another side we have point five B B's a loss from the two connectors so they want to include or not include those connectors in their loss measurement when we go to the service provider world there are 10 30 40 50 60 miles so if the span has 25 B B's a lost its the fiber that leads to the big amount of loss and we don't care so much about one small connector so what that means is if I'm doing a one or two or three fiber reference I connect a source to the parameter with those jumpers and then my screen share I hit reference and then you saw it go from DBMS write to zero and now I have a good reference so what that means is if I had five $100 bills it's saying okay Mike I know you have $100 or $500 it just knows what I have so now when it sees the money I've gained or lost it's got the reference so most power meters you just hit a reference button and it's going to zero it out it's going to know exactly what the source is take an account the jumpers and the connectors so Jeff you'll go to dirt now sure thanks Mike so the next phase that we're gonna get into is how much weirder how much will dirt and debris what will it do to my fibers and things so we're gonna move into inspection on fibers and we have something at V avi that we call IB YC always inspect before you connect I preach it when I'm out there I show them I teach it to them and it's just it's huge because when you get these fiber jumpers you get your new equipment technicians say well the fiber jumper just came out of the bag it has to be clean well maybe it is maybe it's not lice I told you earlier you know I bought a dozen new fiber jumpers and I had a 65 percent failure rate you know sometimes both jump both sides were good sometime one was good the other one wasn't so when I'm out in the field and I'm working with technicians I go out in the field we're gonna work on fiber troubles and things like that it's kind of ironic and I get the same thing from my peers 70 to 80 percent of all the fiber troubles I go out on or dirty fibers you know they assumed or they they you know they said they hit it with a click cleaner a couple times and said ok they didn't inspect and they plugged in so that's huge and then when I look at you know somebody says what's the other 20% what could be fiber breaks um could be something silly like they not make the click on the fiber there's a whole host of things that can happen but inspection and cleaning is the single biggest thing that faces service providers and faces technicians so if we look at these um if we look at my display right now the top left where I show the optical a spiders fiber spider as I call it this is actually another one of those a pcs to PC mismatches where somebody plugged it in that in face broken it it damaged the fiber the other fibers if you look at the cores are basically all covered none of these fibers in this picture would actually be able to transmit transmit data or transmit light down them they're filthy so as you start as like as I work with technicians and I see this all the time and what I typically do and when I talk about inspection and cleaning is I'll put my fiber check Pro software up on the screen like I have here in a minute and I have everybody bring their equipment up and we clean and inspect I mean we inspect everybody's equipment and maybe one time out of a dozen or fifteen technicians I get one technician that's really into the inspection and cleaning and their equipment is pristine sometimes I get in there and I wonder how stuff worked because it's so compacted full of dirt and debris it's what we refer to as the mud pie so I'm gonna bring up on my on my pc software I've got a fiber jumper here and I've got an SC our PC connector here this is a Sam Charlie and I'm gonna plug in and we'll go ahead and inspect this fiber here real quick and it comes back and tells me it fails it says the a zone failed the B zone failed the C and D well next question I get is hey Jeff what are all these zones mean so the a is your core B's your cladding C is the adhesive that binds the outside of the core to the outer contact surface material whatever that whatever that protective material is going to be so in this case I've got a dirty fiber um I may have just taken you know this might be one of those things you just took it out of the bag I'll take my clip cleaner I'll give it a single click and I'll plug it back in here and I have I definitely see some dirt out there in the outer contact area hold it still here there we go so now I've got a B C and D there's some dirt and debris out there in that outer contact area that outer contact area is very far away from the core and the cladding so if this was the only fiber jumper I had I could probably get away with it me I'm the type as I'm gonna hit it one more time and clean it and see what happens so next thing I'm gonna so we're gonna go down to the next slide and we're gonna talk about oils or excuse me uh permanent fiber damage what happens once you know what happens when you continually plug fiber jumpers in because I get this all the time a technicians given their piece of fiber equipment they're given a fiber jumper most of the time they have no inspection no cleaning equipment so again they assume hey my piece of equipment came clean from the factory my fiber jumpers came clean from the factory they keep plugging them in so now what I have is I'm gonna plug a clean fireman to this demonstration using using my software here I have a clean fiber and I'm gonna plug it into a fiber that's got some dirts and de breeze on it so when I make that first mating across that two and a half millimeter ferrule there is 2.2 pounds of force doesn't sound a lot but when I put it across that the fiber itself the actual glass there's 45 thousand psi s so all the dirt and debris just exploded on that initial contact I'll do it a second time on the second one the dirts and debris exploded again now it's starting to cover the core on the third mating it just continually gets worse and worse and on the fourth mating you know at this point I have what's the beginning of the mud pie my core is completely covered at this point not gonna have much success transmitting anything and that was just four times think of how many times if you're out there in the field and you keep using the same jumper you don't clean and inspect what your ports actually look like so I'll transition over to the next slide and the next slide we're going to talk about oils skin oils and things like that so a couple of my fiber jumpers that I got actually had oils on them from whoever put the little plastic cap on them so I'll do a demonstration here in just a second but touching the end face of a fiber isn't necessarily that hard if I go to put the plastic cap back on my fiber I might inadvertently with my finger touch the end of that fiber and I've gotten fibers right from the man facture that way from the person that put them on there did they mean to do that absolutely not but it happened so now I've got oils and things on my um on my fiber end and if I plug those in those oils are going to explode they're gonna they're gonna be shot out with the pressure there in the picture here you know this is f3 I plugged in you can actually see what we call the coffee ring the ring around the outside of the core outside of the cladding there and that is the outer contact area the fiber so what I'm gonna do is I'm gonna take my fiber here and I'm gonna make sure I'm gonna go to my fiber inspection Pro and it's not it's like I'm not sharing that inspection scope here we go sorry ok so I've got a relatively clean fiber here I know I have the dirts and if I add that dirt off there in the outer contact area I'm just good and I'm gonna go ahead and take it here and I'm just gonna dab it on my finger real quick so now I'm gonna put this back in and I'm gonna do an inspection so I put it back into the bulkhead connector and I plug it in and I expect this Oh dagnabbit all I moved it right at the end sorry so now we can see all of the oils and all the oils that I put on from my finger on there there we go much better now I'm gonna take this fiber and I'm gonna plug it into another fiber and this fiber was clean so I'm gonna plug it in there it makes that click I just put 45000 PSIs across it and I'll plug it back in here plug this in give this Center this thing up and give this an inspection take nap at all okay and now you can see all the oils the fiber failed you can see all of the oils that have been dispersed outside and you can also see the coffee ring from the outer contact area so oils and things like that get on fibers and inverting Lee and the and the problem is is if you inadvertently did touch that fiber and you plugged it in depending on the laser source that laser source could basically burn that oil right into the in face of that fiber the fiber that you plugged into in the in face that it's connected to and now you've got damage on both sides because it was burned in so I'll turn this back over to Mike watch my PC software and now we're gonna cover the coffee ring or halo so if you look at the slide there's a question why is your coffee ringing or wise or a halo whatever you want to call it on my fiber and this is a tip a trick for new folks as well as senior folks Jeff mentioned there's a little dome the radius of curvature on the fiber and we contact with me to those two domes like two bubbles meeting baseball baseball bowling ball bowling ball so Jeff just did the oil and we saw a ring the liquid is smushed to the edge of that ring well if I go to my PC software I had this guy connected to a tester for a couple of days and when I disconnect I now see the circle that shows a contact area so you can see the fiber is perfectly clean but there's that ring so when you have the bowling ball bowling ball touching I call the space where they stopped meeting the nook and cranny as airflow comes across we get dirt and that looking cranny so you can see I'm inspecting a jumper with my probe so if I disconnect and see the my ring wipe it off plug it back in and I'm good for 25 years if I unplug and I see a coffee ring and there's dirt plus a coffee ring it was dirty when we plugged in we got that huge pressure holding the connector together all the dirt gets stuck in that nook and cranny and no dirt is going to move to the fiber so this is just another example to show that there's high pressure because there's a dome notice in this case the circle is not perfect when the manufacturers make this thing is they put that bubble or dome on the end of it but it doesn't have to be perfect a circle around the cladding many times it is Jeff's was you can see mine is a little bit off-center but because the fighters clean remove that ring plug it back in and I'm good for 25 years if we go to the next side the question is why is the core visible sometimes and why is it not so this is also a tip and trick we see the slides that one picture has a court and one doesn't so I have a hybrid jumper in my hand we can see that one side is blue and one side is green so I'm going to plug into the blue side and inspect and see how there is no white dot in the middle there is no core so why is that I don't think you could see it in the camera but the Pleau the probe has a little off I could see it there the probe has a flashlight that comes out and that acts as a camera flash this jumper is now hidden in the tips so it'd be totally dark Jeff inspected in bulkheads so it's totally dark a little flashlight and the probe it's LED acts as a camera flash well I saw light into this blue guy it went down there's an angle connector it gives a back reflection so there's no light to come back and be in this core so there's no weight dot in the middle now I will inspect a UPC to UPC you can see I got a blue guy in a blue dye I will now plug in and inspect this UPC and in addition to having dirts on there I got a little white dot in the middle why is that that flashlight goes hits the end of this jumper light comes back down the court let me see the wait dot if you expect an OTDR it's terminated there's nothing for the light to hit and bounce back so oh D D ours won't have it if you inspect at a patch panel it's connected to miles of fiber that's killing back reflections if you didn't expect at a patch panel and you saw some weight light then you can expect the dirty connector several feet away causing back reflections if you don't see the core it is there if you using a digital scope and it's passed failing it it's gonna look for dirt in the center if there's dirt is gonna fail but if there's no dirt and you don't see the court it's gonna pass and the fiber is going to work fine the next question is is the dirt on the fiber or on the lens on the next slide so this is a common question we get how do I know if the fiber is dirty or if my camera is dirty so if I inspect the fiber I will plug in a jumper into my camera I see some dirt on there if I spin the jumper notice how the dirt is moving I spin the jumper the other way the dirt is moving if the dirt leaves it's on the jumper if the dirt does not move it's on the camera so with most probes you remove the tip there is a lens right there now take an optical wipe wipe it clean it and then your scope is good if you're expecting bulkheads or jumpers and you're not spinning it and you see the exact same piece of dirt on ten fibers in a row maybe that's time to think about is the dirt on my camera or is the dirt on my jumper now turn to slide over to Jeff and he's gonna talk about some more inspection as well okay thanks Mike so when we do inspections this comes down to really what I refer to as tips and tricks you know I want to do this and out when I inspect fibers I want to do this as efficiently as I possibly can so if you have a if you have some type of digital microscope we have a P 5000 die in a fiber check Pro and they both use the same they'll both use all the different same inspection tips so right here I have a bulkhead tip for an APC and then I have a tip that goes right over the end of the fiber and the one thing that you'll never ever see me use out in the field is I'm never going to use this fiber to this inspection tip that's actually gonna plug in and go directly over the fiber itself and the reason being is very simple if you give me a fiber jump or we're out two and we're out to do an install and I have a fiber jump or the typically asked technicians hey how many inspection cleanings do we have well they'll say well - I've got my fiber jumper right here got the two ends I said yeah but what about what you're gonna plug in - oh yeah we got to clean those - huh yes you have to inspect you have to clean those two so now if I take my fiber tip and items and I plug it in and I go right over top of the end of the fiber I can inspect both sides make sure they're clean do all that life is good but then I have to go and I have to take the tip off that and then I have to put my bulkhead tip on to go into the bulkheads of the equipment so what I do is I tell technicians get yourself bulkhead adapters so I've got a bulkhead adapter here this one happens to be a SC PC it's blue so what I do now is I take my PC bulkhead adapter and all I'm gonna do is I'm gonna plug this thing in and now I can do my inspection right through here so I'll come over here I'll do my inspection and I'm clean so once I know that's clean I can unplug from this and then go over and plug into my bulkhead on my equipment and do the inspection there if it's dirty then I can clean it I can can you know continue the inspection clean till they're both clean now I can plug the st. now I can unplug my fiber from my bulkhead adapter and plug it directly in and it's clean I didn't have to switch tips also the problem with switching tips that I find out in the field is once you take that one tip off and you set it down did you remember to pick it up and put it away before you left a lot of technicians will tell me yeah I can't tell you how many tips I've lost I'm now down to a couple so I'm having to use bulkhead adapters that's wonderful um so I've got you know I've got bulkhead adapters I've got blue for PC connectors I've got Elsie's out there as well I've got eight pcs I actually also have a SC on one side and an LC on the other so the question is hey tonight's inspectin if I've got a jumper that's going from an SC to an LC connector can I use the same inspection tip absolutely so I'm gonna take my I'm gonna take my tip here and I can plug into the fiber and I can plug my LC in oops wrong side wrong one sorry I can plug my LC connector in and I've got an SC tip and I'll plug that in and I can now do my inspection even though I've got two different types of tips I've got a bulkhead adapter that allows me to inspect the smaller LC with the SC so again I'm all about efficiency out in the field and they make these inspection tips you know and amid the bulkhead adapters they make them in green for a pcs they make them in blues for PCs and things like that the next question I get is every now and then I get a technician that calls me and says hey Jeff we're out here doing some inspecting and all of a sudden my inspection scope stops working I can't get anything all I'm getting is a dark picture it's not focusing I've tried manually focusing it I've tried to autofocus it I've tried to do this I've tried to do that and nothing's happening and I got to be honest with you when I first got into fibre and I was doing inspection I got bit by the same bug so having done this a few times what I do now is I ask the technicians okay what type of fiber jumper do you have in your hand what color is the connector and they said well it's blue or it's kilts in this case they'll say it's green I said okay so I've got my APC right here and I said okay so they plug it into a bulkhead adapt captor in my case and I said what inspection tip do you have on there well heck I don't know I just got an inspection tip on there go my bulkhead so they'll describe it to me and I said is it round or is it angled at the end you said no it's got a round connector oh there's your problem right there you're plugging a PC into an APC connector so remember the APC connectors is manufactured at an eight degree angle so when I plug this in and I do a live demo no matter what I do here I'm not gonna see anything I can try to auto test an auto Center and auto focus and do all those things all I'm gonna get is dark where I'm gonna pick out the outer contact area and things or sometimes I may pick up a Halfmoon but I'm not gonna be able to inspect this fiber and actually see what's going on when I have that mismatch so it's one of the it's one of the common things that happens and it's just like oK we've been doing so many UPC's and now I have an ATC so hopefully that makes sense hopefully those tips and tricks make sense get yourself some bulkhead adapters get type that you need to do your inspection and that way you can typically use either the APC bulkhead tip or the F or the SC bulkhead tip to do your inspections Mike hand it off to thank you Jeff let me launch my pc software and then on the next slide we see des cleaning on a shirt or blue jeans work this is rhetorical feel free to type in some comments so what I'm gonna do is gonna try it there are dress shirts many times they are silk gore-tex or something fancy many of our work shirts are cotton or flam so I'm gonna throw up some Faneuil flannel on my shoulder and I'm going to clean this guy one two I'm gonna rub them I pull them across my flannel cleaning on my shirt of blue jeans several times so now I'm gonna ask you if it's clean because I just cleaned on flannel and what my technique in the field to do is I get people tell me they do all kinds of tricks there are few tips and tricks I say are you betting launched that what you just did worked they normally say wagering is illegal at this establishment I'm like wait a second I just bet you $10 barbecue banana cream pudding and you won't take it but yesterday you did a hundred times on stuff that cost thousands of dollars on a multi-million dollar network at a multi-billion dollar company so if you're not going to bet me ten dollars in a training environment don't do it on your network so now I will plug in this fiber and I will inspect and it's permanently damaged so you say well Mike you tricked me normally it does get off dirt well first of all there's stubborn dirt it's caked on baked-on like a mud pie because of pressure temperature humidity a shirt ain't gonna get that stuff off next if there's permanent damage cleaning doesn't get off permanent damage if you don't believe me go to your truck where your vehicle take some pebbles cracker windshield and then try to clean it it doesn't fix it if you have airborne dirt on on there sometimes a shirt or blue jean works just fine earlier I did this today with Jeff and I ran it across that flannel and I had two big pieces of lint coming across the hole a fiber so in that case it might remove dirt but I picked up lint so if you're cleaning on your shirt my question is how do you clean the bulkhead here is a bulkhead the fibers sit way back there about a half of inch I said how do you clean your shirt that one guy and he said I take my shirt off I was like okay we don't need no a sensitivity class to realize that you're joking but what he's saying is I do not clean the other side of my connector so the example that I use is take your eyeball glasses put them in the mud and clean one side you never do that with your eyeball glasses so don't do it with your network if you go to the next slide now we have cleaning materials and we could take these via QA wipes our common optical grade wipes not tissue that picks up lint they're fine for jumpers but jumpers only there's cassette cleaners I have a blue one P top is famous one it's green they clean jumpers only then we have cleaning sticks different kinds for 2.5 and 1.25 most of them click you can hear that click here's a click put on a cap this cleans an LC jumper take off the cap this cleans the LC bulkhead so I can get in the bulkhead some people say sticks don't work that's because here's an example there was two dirts on one fiber the guy creek that said is not working I was like give me that I clicked it that was one dirt I clicked it there was zero doors so you get one clean pore click also some of them have a button push if you push the button that pulls the tape across the cleaning sticks the tape comes flat across and does a 180 twist so just because you get one clean per click does not guarantee it's going to be clean let me make your windshield or your window or Mir dirty and then bet some money that you can clean it with your eyes closed with a paper towel so you get cleaning per method but the only way to verify that is clean is to inspect it that stubborn dirt is not going to come up to the dry clean and I just tricked you with that Pro damaged cleaning ain't gonna fix a cracked windshield right you they gotta get that free resin that goes in there or if it's cracked you got to get you when she had replaced so that's a little overview on inspection and cleaning and then we can go to Q&A to see if there's more questions on the different types of cleaning materials that does include our presentation in terms of slides camera and screen shares we appreciate your time today hope you learn something whether you're new or senior and now we'll see if there's any additional questions s'okay closing remarks we covered different fibers single-mode a multimode long haul short haul we covered loss we covered reference we covered EBS and DBMS we covered a PC and UPC we covered bends we covered inspection and we can cause permanent damage different ways to inspect different ways to claim so if you're new hopefully it helped if your senior hopefully you picked up some tips and tricks if you already knew hopefully now you have some stories to explain to your new folks you can take a shortcut in cleaning but there's a risk of permanent damage even if you don't cause permanent damage you can cost two three four five six TVs a loss you got a multi-million dollar system and systems not working and my time I've had two people say I clean up my skin I jokingly thought I jokingly said you need to use the Parral and the person so that I did use parrell I'm like well let's check the label it's not fiber grade touch that fighter like Jeff did all of us have oil is gonna be goood out and now you plug it in you causing loss and that laser can fry it in there and cause permanent damage so we appreciate your time today it's session is available if you need to relook at it or have some other folks look at it thanks Mike you know as for my closing remarks just remember if you're new to fiber this can be intimidating and don't just assume that hey my fiber jumpers are clean everything is clean as Mike and I said and what we see out there in the field 70 80 % of stuff that we go out on our silly mistakes you didn't clean and inspect your fiber you assume they cleaned and now they're dirty connectors and they're causing they're causing loss they're causing other issues that we pick up with the road TDRs and some of our other equipment so neveress never make an assumption that something is clean always clean always inspect one thing I'll bring out as the LC connectors so I have an LC connector here somewhere and they're very small so when you have an LC connector patch panel and I've been out with technicians many many times we're gonna unplug a fiber to do some testing and they get their fingers in there and they inadvertently think they have hold that small LC connector they unplug and they inadvertently unplugged the fiber next to it then they stick it right back in there and I'll typically want to stop them and say you know remember that outer contact ring that Mike talked about the longer it sits out there the more dust and debris and things that are collecting around it and by unplugging it chances are something may have fell down in there when you plugged it back in even though it was only for a split second so you may get lucky and say hopefully this didn't put a problem but if you put a trouble in there how many hours is it gonna take to get that report to come in get somebody dispatched and somebody to get out there and work on that it could be five six seven eight hours at another customers out of service because you and inverting Lee unplugged so always inspect and connect go ahead oh so question can the P 5000 I connect to the iPhone microscope the answer is no iPhone does not allow a USB to the iPhone connection and for our mobile for our mobile software to bring it up it works just fine on on the androids and things like that the galaxies that are out there but it doesn't work on the on the on the iPhones with the iOS system I guess Mike you want a I guess the question is how is it fouled if it's dirty you can you know you can always clean it if it's scratched or pitted and chipped there's no repairing that unless you want you know cheaper to it's cheaper to go ahead and just put another fiber Jumper in there than to try to polish it out my comment on that one comment on that the pass and fail standards they realize how hard it is to keep a fiber clean and pristine and perfect with no dirt so the cable manufacturers and network equipment manufacturers they have a pass/fail standard if you have a digital scope that does pass/fail it's gonna go against the IEC standard and then there is also a ti a standard for enterprise and then building people that use that same IEC standard it does a lot for some dirt the other scenario is you have some red dirts it fails but the fiber will work so that is possible but the reason why I fails as Jeff mentioned if you have free dimensional dirt and how do we know if it's three dimensional when you plug in that dirt can explode and move around so we can fail you plug in and it works and then you unplug over time and then all of a sudden that thing that failing to work is not failing and not working so it's up to you guys people plug in dirty fibers all the time and they work they may fail later they may cause permanent damage but if it is not working and it's permanently damaged a dryclean don't get it wet clean don't get it then the solution is replacement so a couple items if we're doing an OTDR and inspect it at the same time we can have it set up so now we see fiber one inspection fiber one OTDR fiber two inspection fiber two OTDR in terms of editing it depends if you want to change the fiber name the cable ID you made a typo then we can go and edit job type information but we can't change any of the parameters so if you have an inspection image and it fails its failed you can call it a different number you can call it a different name maybe you say fiber one initial fail fiber one pass after replacement so you can't change any of the data and we have a timestamp so if you inspected at a certain time and they all failed and you went somewhere else like wait a second why does this say Saturday at noon when nobody's allowed on mooting on Saturday so the time step helps to confirm that the work was done at the right rate time and then the other possibility now is geo stamping where we can look at the time stamp but we can lost also look at the geolocation so we see testing was done at the job site and not a much truck at the Walmart or I'm just faking results so editing on actual results not editable but editing job info is editable yeah I've got a I've got a fiber here Mike I'm gonna grab control from you and I'm gonna shares give me a second here so while he's pulling that up the other scenario is sometimes there's a pit chip or a hole it appears to be white dirt that's like there's a gouge in the glass so you all the dirt we've been looking at is mostly black well if you see a white piece of dirt it could be a hole a chip it appears white and then sometime there's a whole bunch of dirt it causes so much horrible back reflections that it just appears to be white but once again dry clean it wet clean it if you do the wet clean dry it off but if you wet clean three four or five times and you're not positive exactly what you look at it and at that point it becomes a permanent damage and just pull it up a scope so okay so that so right here I go ahead Mike but does that mean we talked about the fiber are we talking about on the scope so right here I've got this and this is that a PC to PC mismatch and you can actually see the the chips the chips and the pits and the scratch that goes across there it's actually reflecting light back and you can also see other other chips in there that are reflecting the light back that's permanent damage there's no amount of polishing or anything else that's gonna take that out of there short answer though is yes if the fiber is a damn it then we can see a pit we can see a chip we can see broken glass I had one where the APC was plugged into a UPC first of all was single mode a PC plug it into a multi mode that should not have been done garden hose goes a garden hose fire hose goes to fire hose well he has taken a single mode which is a small quart like a garden hose and connected to a multi mode which is a big core like a fire hose and then he did a PC to UPC mismatch and then add actually exploded the fiber so it just had a bunch of cracks all over the place if I couldn't identify that it was a crack or damage I would just haven't looked at it and say this thing is horrible it's not transmitting any traffic has to be replaced so we'll both take that one my answer is is no and if we can see my camera I'm holding it up if I take a tip off that's the end of my lens and the camera is inside of the probe so if our lens gets dirty we can wipe it off I also say we could take a picture through a screen because we focus out so there's commonly a little bit dirt on the lens and we still can see but I was on one session a long time ago I said in four years I've had three pieces of dirt on my mine lens and then I inspected and there's a big old lint coming all the way across my lens that I could see in the display I was like okay it's been five years and now I have had four pieces of dirt so once again we tell you to spin the jumper if the dirts not moving it's on the lens now you can wipe off the lens and get that thing clean and go back to inspecting you know we said optical wipe because we can use Kleenex and boy if I was in a jam and I didn't have anything I'm gonna use whatever kind of cloth I have but we don't want to scratch the lens right you have eyeball glasses you have these special cleaners tissues gonna leave a bunch of lint and junk on there but any wipe throwable comfortably optical is gonna get the dirt off fat now when you put the probe in a lot of times I'll see text take off the tip and put the probe in like this well now that's a lens and now it's not about getting dirt on it it's cracking it chipping it busting it messing it up so I always leave a tip on to protect my lens and I don't take this off sometimes we have to just switch to a specialty tip but leave this guy on so you don't get no mud pie down in your camera Jeff and I commonly fly every week and I have a probe I take it on the airplane I go on the sky pressure a temperature change and when I land I go to my next site I expect that I'm gonna be able to open up that probe and not have any dirt on it so I don't have no plant maintenance period do it every six months do it every year if you see some dirt on the lens wipe it off and do it like I said happened to me three times in four years and right when I said that as I Oaks it happened to be four times in five years so no plant schedule for me you spin the fiber and the dirt stop move and it's on the lens wipe it off but make sure you do detect that lens by put a tip now the JD issue I turn a vib probes we can actually take the tip off so if you did drop this and smashed it to pieces it's not a repair you can add a low-cost order a new lens put on a new lens and your cameras still good if your lens isn't removable and you break it now you have to send your lens back in for repair one other thing I'll add to that question is and I get this question sometimes is hey I've got a bulkhead and I noticed Jeff you're always cleaning you're always inspecting to your bulkheads and it's got this it's got the hollow sleeve in there how often do I need to clean that hollow sleeve to be honest with you I've never had to clean one um could dirts and de breeze get inside one sure and could that impart on the de fire yes but I've never really seen it happen in the field I say it could you know in theory it could happen but that's not one of my priorities is worrying about whether this is clean I'm more worried about your fibers and your in faces and everything else or they are they actually clean yeah I agree there and to me you have to drop it into a mud you have to drop it outdoors you dropped it in blood puddle at that point it's just a hollow shaft you can use whatever you want water sink get all that crud throw some swabs in there make sure that shaft is empty but we get that question a lot hey if I plug into a mating adapter it's gonna get dirty well we connect to a network those little mating adapters in the patch pan and we plug into optics we're sticking down a shaft all the time so it's possible but extremely extremely we're for that to cost dirt to get in the fiber unless there's some kind of mud pie in there because we dropped it in the mud okay we have another question from a bard torgan Santa can you please take a quick through inspection profiles so Jeff you want to go to screen share your shirt uh yep I'm so the ieast okay I'll let you go to your screen share Jeff and I'll talk the itis standard cost money so somebody can order it but if you go to the scope and you go to a profile profile i'ii see you can look at the profile and it shows you the user what dirt is allowed so some of them I don't have memorize at all I think the IEC single-mode says no dirt in the core no dirt bigger than 5 microns and the cladding you can have small dirts as long as they're not too big no dirts out there and Zone C which is a content area bigger than 10 microns so you can go and look at the profile and see exactly what the specification is I had one company call I think he was a VP so my texts say you're failing all of my fibres can we have a call and I said sure so we had a call I said I'm going against the IEC standard that comes from the manufacturers of equipment the cabling the providers so I pass a fairly good Zack I said if you want to treat your pass/fail you can but now you go to these big multi-billion dollar companies and third-party companies and say hey I'm passing this or failing this well then the the VP said how many of these fail the guy goes for he goes replace him now so if everything is clean and they had thousands of fibers they had replaced for so keep it clean you're gonna pass and Jeff you got the profile so that shows um there's also uh notice how it says addition to addition to allows for a bigger zones see we would fail a lot because in that epoxy ring if any of the dirt text don't be it would fail and then you can go into the scope settings and if you open a profile it would tell you exactly what it is no dirt allowed on the core and if you want to create your own then you could do that as well so I break that up yeah he just hit view and you can see made meet a little small but I see zone a and it says scratches and it just says defects so rather than us talk if you have a scope you should go and look it up and see exactly what is allowed or disallowed once again you can fail and the favorite works but the reason why fails is they don't know if I three-dimensional dirt they don't want it to move around and cause permanent damage or a get get migrated over to the core so hopefully that answers that question if not you can follow up so we're still here if you'd like to ask more questions Mike and I will be here we'll give you a few more minutes Mike anything you want to add while we're waiting for more questions well I appreciate the time if you like to drop go ahead and go go ahead but if you like to ask some questions go ahead and type them in and also remember this was fiber basics inspection cleaning handling optics connectors some tips hey I can expect this Sam Chari with ally machardie or that kind of stuff if you have a top of you lied to cover for your market space the cable telecoil in turquoise a lot of us are all doing the same thing nowadays then chat in and request and we can cover that so we do have a one additional question from Jaime Burgos how much optical power kind of microscope support okay so what I think that means is we hop on to a live fiber and the scope is gonna get hit by live fiber so I did it today and I was coming out about next Reedy p.m. so when I showed you that the scope was seeing 1310 I'm sitting about zero and it didn't hurt my scope I don't know if there's a specific spec I think at some point and I've shot red light right into it and just saturated the whole thing so I think in general is not going to damage the camera and another scenario is if we think we're expecting unlit fiber a dark fiber a fiber with no traffic and you're at 850 1313 10 and you see a bunch of weight light in there you need to say why am I seeing light via my scope when this fiber has no light on it my class is unlit fiber that as traffic on it is not on lit its lit and you have to be the person who brings that down and the old days with Jeff and I old timers it was three days to pay for a t1 if you bring down a 10 gig you might call that a resume generating event or a career changing event so if your scope is saying there's light on there I'd be worried less about damaging the thousand dollar or two thousand dollar scope as opposed to bringing down an entire state or an entire region so ideally that should never happen because we expect the fiber to be dark when we unplug it from a network and to piggyback on what Mike said at 1310 you were able to see that light if you plug into a live fiber at 1550 you're not gonna see it and Mike I don't know about you but I've never heard of anybody saying I burnt my scope out because I plugged into a live fiber accidentally just never seen that anybody say got fried same you know not work we work we both work a lot with cable providers and cable providers tend s tend to have a lot hotter signal than the telco service providers out there and I know we've accidentally plugged in the live fibers before not again I've never heard of anybody doing damage to the scope so any further questions if you have any comments in old days we would do slide presentations right hold all questions in the ends so we try to mix it up today show the camera go to live shots so if you have any suggestions suggestions nice positive constructive criticism too close to the camera too far away bring the camera out if you have anything like that you'd like to share for us they go ahead and we'll just try to make it better the next time we do it they told me we are doing a YouTube live I'm like is that at the mall I don't even know what a YouTube live is and I was like you to be so trying to change it up a little bit make it more interactive make it more like we're there in person so if you have some comments feel free to send them yeah this was our very first YouTube livestream so we'll learn a lot from it and will improve and we'll make changes as we go forward and there are an arrant into our next segments and things like that but any feedback that you can give us would be great well general we're

YouTube channels and our youtube.com pages so please encourage you there are some links to glow in the description of this livestream that can either take you to learn more about fiber communications with fiy avi solutions and fiber testing if you need to contact sales there is a link down there that you can contact sales to talk about fiber inspection equipment and then there's also a link to our how to product you know channel for more how-to product videos on learning how to do Oh TV our inspection fiber inspection all types of different testing stuff that we do here at V obby over You gentleman for a final closeout well thanks happen for that and then one thing we do as engineers is somebody said hey how do I learn about the profile well you can pay money for the IEC standard or open the software so a lot of times we do make quick cards which are in writing a lot of folks not prefer videos so we can go to laptop make a three minute video if you want to learn what the pass/fail is for each profile here's how you do it the same way somebody said we want to combine our inspection image with our OTDR results from memory I don't know if you have that video but if that's the case I know we got a quick card for it and we just say okay we'll crank out a three-minute video you know how to use the OTDR you know how to use a scope now we just watch a three-minute video that shows how to do it so folks need assistance for something they're trying to do whatever the product is then we try to make videos three four five minutes right now to our webinar where we
